CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 380,201, datedMarch 27,18,88.`

Application filed March 7, 1887.

.To all whom t may concern:

Be vit known that I, HENRY A. GORE, a citizen of the United States, anda resident of Goshen, in the county of Elkhart and State of Indiana,have invented certain new and useful Improvements in Carpet-Sweepers;'and I do hereby declare that the following is a full, clear, and exactdescription of the invention, whichwill enable others skilled in the artto which it appertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification, andin which- Figure 1 is a bottom view of my improved carpet-sweeper,showing the dust-receptacles opened. Fig. 2 is a vertical sectionalviewon line w m, Fig. 1. Fig. 3 is a side view of the sweeper, showing partsin dotted lines; and Fig. 4 is a horizontal sectional View on line y y,Fig. 2.

Similar numerals of reference indicate corresponding parts in all thefigures.

My invention has relation to carpet-sweepers; and it consists in theimproved construction and combination of parts of a sweeper, in whichthe brush is provided with vertically-yielding bearings and thedrive-Wheels are provided with horizontally-yielding bearings, ashereinafter more fully described and claimed. p

In the accompanying drawings, the numeral 1 indicates the casing forthe'sweeper, which is provided with the usual pivoted bail,y 2, for theattachment of the handle 3, and which has the yielding ,fender-band orcushion 4 secured around it, and the bottom of which is provided withthe pivoted dust-receptacles 5.l

The ends of the casing are provided with Afender-bands or strapA metal 6and the end 4o pieces of the casing have vertical slots 7 open vat thelower ends.

The brush'8 is provided with pulleys 9 at its ends, and is j ournaled ontrunnions or bearings 11 on the free ends of two horizontal strips, 12,of spring metal, secured with their ends to the side pieces of thecasing and in the end pieces of the casing.

bands, having their free ends at'the middles of the straps registeringwith the vertical slots The drive-wheels 14 are provided with the eyusual yielding tires, 15, and are journaled upon theoutwardly-projecting bent endsv16 of two springs, 17, secured at theirmiddles to the top pieces of the casing-one uponeach side of the brushand extending longitudlnally of the casing-and having their ends bentrst downward toward the brush and thereupon outward through thehorizontal slots 18 in the end pieces of the casing. It 6o;V

will thus be seen that'the brush may yield and conform to unevensurfaces in the carpet and may at all times kbe ata level with thesurfaceof the carpet, and as the brush` and its pulleys are forced up or`down at one end or the other of the casing the pulleys will at alltimes be in contact with the drive-wheels, as if the pulleys of thebrush are'i'orced upward, bringing their centers at a vlevel with thecenters of the drive-wheels, the latter are forced to the sides againstthe springs, which will force them toward the middle of the casing assoon'as the pulleys of the brush are lowered, the springs and thehorizontal play of the drive-Wheels bringing them into contact with thepulleys of the brushat all times. This will obviate the inconveniencesexperienced in sweepers having vertical yielding play for .thedrive-wheels, as in these machines the pulleys upon the brush will beout of contact With the drive-wheels Whenever the relative positions ofthe brush and the wheels are changed from the normal positions, as whenthe casing is depressed by pressure upon the handle the bearings for thewheels yield and allow the brush to be depressed against the carpet. Ylt follows that the construction of the cas- Y ing and its parts may bevaried, as found most convenient, and the brush may likewise be providedwith its bristles in any desired form and' manner, as I make noclaim/upon any parts ofthe machine, excepting the bearings for thebrush. y

Having thus described my invention, I claim In testimony that I claimthe foregoing as my and desire to secure by Letters Patent` of the own Ihave hereunto affixed my signature in United Statespresence of twowitnesses.
